Dear future millionaire,
I have been building, testing and using opt-in lists to grow my business since February 2000. Over the years I have uncovered what works, what opt-in lists produce results, what lists are popular, and why it's important to keep adding other people lists and lists you own to your marketing arsenal.
Here's the problem.
You may already belong to dozens of lists but, do you know the critical things you should know about each list you use?
